The M640V is an advanced, infrared-capable rifle light that features a new low-profile mount for maximum versatility. This lamp can be easily and securely attached to MIL-STD-1913 or M-Lok rails. It produces 350 lumens of white light and 120 mW of IR output, selectable by simply turning the lens ring. The proprietary TIR lens provides a long-range, intense beam of ambient light. The robust construction made of hard anodized aluminum and O-ring seals makes the lamp durable and ready for use.
